13. a) Tools of Central Bank Policy: 13 These are the three Shifters of Money Supply

14. 3 Shifters of Money Supply 5 points for complete response for each shifter The FED adjusting the money supply by changing any one of the following: 1. Setting Reserve Requirements (Ratios) 2. Lending Money to Banks & Thrifts Discount Rate 3. Open Market Operations Buying and selling Bonds 14

15. #1 Using Reserve Requirement 1. If there is a recession, what should the FED do to the reserve requirement? (Explain the steps.) 15 2. If there is inflation, what should the FED do to the reserve requirement? (Explain the steps.) Decrease the Reserve Ratio 1. Banks hold less money and have more excess reserves 2. Banks create more money by loaning out excess 3. Money supply increases, interest rates fall, AD goes up Increase the Reserve Ratio 1. Banks hold more money and have less excess reserves 2. Banks create less money 3. Money supply decreases, interest rates up, AD down

16. #2. The Discount Rate The Discount Rate is the interest rate that the FED charges commercial banks. Example: If Banks of America needs $10 million, they borrow it from the U.S. Treasury (which the FED controls) but they must pay it bank with 3% interest. To increase the Money supply, the FED should _________ the Discount Rate (Easy Money Policy). To decrease the Money supply, the FED should _________ the Discount Rate (Tight Money Policy). DECREASE INCREASE 16

17. #3. Open Market Operations Open Market Operations is when the FED buys or sells government bonds (securities). This is the most important and widely used monetary policy To increase the Money supply, the FED should _________ government securities. To decrease the Money supply, the FED should _________ government securities. How are you going to remember? Buy-BIG- Buying bonds increases money supply Sell-SMALL- Selling bonds decreases money supply BUY SELL 17

18. b) Quantity Theory of Money If the real GDP in a year is $400 billion but the amount of money in the economy is only $100 billion, how are we paying for things? The velocity of money is the average times a dollar is spent and re-spent in a year. Quanity Theory of Money Equation: M x V = P x Y M = money supplyP = price level V = velocityY = quantity of output Notice that P x Y is GDP 18

19. c) Nominal vs. Real Interest Rates Nominal Interest Rates- the percentage increase in money that the borrower pays including inflation. Nominal = real interest rate + expected inflation Real Interest Rates-The percentage increase in purchasing power that a borrower pays. (adjusted for inflation) Real = nominal interest rate - expected inflation Example: You lend out $100 with 20% interest. Prices are expected to increased 15% In a year you get paid back $120. What is the nominal and what is the real interest rate? The Nominal interest rate is 20% The Real interest rate was only 5% In reality, you get paid back an amount with less purchasing power. 19
